Abstract
The utility model provides a rotary open-fast indoor hydrant which is composed of a valve body component and a rotary joint component which are connected, wherein, the valve body component is provided with a butterfly valve, and the rotary joint component is provided with an L-shaped rotary joint and a rotating joint. Therefore, at the time of fire protection, the utility model has the advantages of convenient operation, high water output speed, and controllable water output. When the KN type fixing interface of the utility model is matched with a corresponding fire hose, the KN type fixing interface which is not folded and is not twisted can rotate back and can rotate for achieving the purpose of rapid fire protection.
Description
The utility model relates to a kind of fire hydrant, particularly a kind of indoor fire hydrant.
Indoor fire hydrant is to connect running water pipe joint and the essential instrument of fire hose, but existing indoor fire hydrant often makes fire hose give a discount in fire-fighting work and makes troubles to fire-fighting work, in order to overcome this deficiency, there are many swinging indoor fire hydrants to arise at the historic moment, it is 90203712.9 that the utility model patent communique discloses an application number in the recent period, notification number is the utility model patent of CN2076429U: the swinging indoor fire hydrant, indoor fire hydrant its valve body one end bearing on coupling nut, make the fire hydrant hose coupling wholely turn round 360 °, coupling nut directly is connected on the running water water-supply-pipe, the other end of valve body is attached at fire hose and connects and buckle, thereby make the indoor fire hydrant can be with the required azimuth rotation of fire hose, avoided fire hose discounting phenomenon, but the water yield during owing to the utility model work is to be controlled by screw thread, make inconvenient operation, it is slow to go out water speed, when its interface is mixed the work of corresponding fire hose, distortion easily, and the joint of fire hydrant can turn round when fire-fighting work, just do not change when not working, so still make troubles to fire-fighting work.
In order to overcome above-mentioned deficiency, the purpose of this utility model provides a kind of improved swinging indoor fire hydrant, makes when fire-fighting work, easy to operate, water outlet is fast, when its interface is mixed corresponding fire hose, do not give a discount, non-warping, whenever interface all can turn round.
The purpose of this utility model realizes by following technical proposals.
The utility model is connected with the swivel coupling assembly by valve component and constitutes, valve component is by valve body, valve seat, butterfly valve, control stick, handle and gland are formed, the swivel coupling assembly is by L shaped swivel coupling, swivel joint and KN type fixed interface are formed, valve seat places in the valve body and with valve body fixedlys connected, butterfly valve places in the valve seat and with valve seat and flexibly connects, body wall has a tang, gland covers on tang, butterfly valve is made up of flap and valve rod, valve rod passes tang and gland is fixedlyed connected with control stick, control stick and handle flexibly connect, the lower end and the running water pipe of valve body are spirally connected, its upper end is connected by the end of steel ball with L type swivel coupling, one end of swivel joint is connected by the other end of steel ball with L type swivel coupling, and its other end and KN type fixed interface are spirally connected, and fire hose is connected on the end of interface.
The utility model water outlet is fast, and water yield can be regulated arbitrarily, when working and not working, its swivel coupling and swivel joint all can turn round and rotate freely, in the fire-fighting work process fire hose do not give a discount, non-warping, in addition, the utility model volume is little, and cost is low, easy to operate.
Below will be described in further detail the utility model by specific embodiment.
Fig. 1 is a structure chart of the present utility model.
As shown in Figure 1, the utility model is made up of valve component and swivel coupling assembly, valve component is by valve body 4, valve seat 5, butterfly valve, control stick 17 and handle 14 are formed, the swivel coupling assembly is by L shaped swivel coupling 9, swivel joint 12 and KN type fixed interface 13 are formed, valve seat 5 with place valve body 4 in and fixedly connected with valve body, and interference fit, butterfly valve is made up of flap 1 and valve rod 2, flap 1 is fixedlyed connected by screw 6 with valve rod 2, butterfly valve places in the valve seat 5, valve body 4 sidewalls have a tang 19, there is a gland 18 it to be covered at tang 19 places by being spirally connected, valve rod 2 one ends and valve seat 5 flexibly connect, the other end passes tang 19, gland 18 is fixedlyed connected with an end of control stick 17, handle 14 flexibly connects with the other end of control stick 17, in order to increase sealing, between valve rod 2 and tang 19, be distributed with several O RunddichtringOs 15, between tang 19 and gland 18, be equipped with cushion cover 16, between valve body 4 and valve rod 2 one ends, be equipped with small ball 3, so that valve rod 2 activities freely, the lower end of valve body 4 connects the running water pipe joint, its upper end is connected with the other end of L shaped swivel coupling 9 by steel ball 7, its interface has two O RunddichtringOs 8, swivel joint 12 1 ends are connected with the other end of L shaped swivel coupling 9 by steel ball 10, its interface has two O RunddichtringOs 11, its other end and KN type fixed interface are spirally connected, fire hose connects on the other end that snaps onto KN type fixed interface, O RunddichtringO 8,11 all are provided with in order to increase sealing.When the utility model was not worked, L shaped swivel coupling 9 can rotate arbitrarily, is convenient to reduced volume like this and places Fire Hose; In the time will making the utility model work, depress control stick 17 as long as hold handle 14, flap 1 rotates unspecified angle under the drive of valve rod 2, running water just can flow out from fire hose, by handling control stick 17, the just controlled water yield of making, when the angle that turns over when flap 1 is 90 °, the water yield maximum, rotate L shaped swivel coupling 9 and swivel joint 12 can make fire hose non-warping, do not give a discount, thereby reach the purpose of quick fire-fighting.
